Obs. I inserted, as a reference to the young of this species, the 

 Peribolus of Adanson. M. Blainville, who has lately re-established that 

 genus, observes, that Adanson positively says that he has seen the young 

 and adult of his Potan; but I do not observe any such remark in Adan- 

 son, who only describes the young specimen of his Potan as being of a 

 violet colour. Now this agrees with the youngest state of the shell to 

 which I have referred it; and on re-examining the subject I am not in- 

 clined to alter the reference, as I have seen a series of specimens which 

 most completely connect the stages. Adanson' s genus Peribolus con- 

 sists of this young Cowry and three species of MargrtneZ/a of Lamarck; 

 and, as he does not give any character, it is now quite impossible to 

 know by what character he separated it from his genus Porcellana, the 

 Margrme/Za of Lamarck ; which w\X\\ the genus Cyprcea and Peribolus 

 form his family.
